2019725These backup rolls are larger and contact the back side of the smaller rolls. A fourhigh mill has four rolls two small and two large. A cluster mill has more than 4 rolls usually in three tiers. These types of mills are commonly used to hot roll wide plates most cold rolling applications and to roll foils. Details
Hot rolling is a mill process that involves rolling of steel at a high temperature, which is above the recrystallization temperature of steel. The high-temperature steel is allowed to pass through one or more pairs of rolls to reduce its thickness or to make its thickness uniform i.e. to form coils. The process is much similar to rolling of dough.
Lewis, Continental, and Bliss were attributed to building some of the largest rolling mills in the world before World War II. In fact, Mesta and United pioneered the rolling process to reduce very thick as cast slabs into plate, the plate into hot rolled coils …
The POSCO Quality Hot Rolled Steel Hot rolled steel products are divided into two groups: hot rolled coils produced through hot rolling and hot rolled steel plates, which are made by cutting material from hot rolled coils. Slabs …
Hot rolled dry sheets and coil are a darker grey than most other steel types and have a silvery blue, almost purple strip along both sides. The color of the strip makes the steel's surface appear as if it is still hot to the …

This material is manufactured by re-rolling and cold reduction of hot rolled steel sheeting. The first step taken in the process is when a hot rolled steel coil is unwound and passed through rolls which flex the plating in such a manner as to break and fragment the mill scale.
NKMZ rolling mill rolls are made with alloy forged steel with Chromium content of 2%, 3% and 5%. They are used in different types of rolling mills such as conventional hot strip mills, steckel mills, heavy section mills, 4Hi and 6Hi cold rolling mills, and are advantageous for the rolling of steel and stainless steel, aluminum and other non-ferrous alloys.
Hot Rolled Steel Coil. Hot rolled steel coil provides excellent properties, like high strength, high toughness, and good weldability. It is widely used in construction, machinery, boiler, pressure vessel, and other manufacturing industries. It is also material for cold-rolled products and galvanized steel products.
The hot rolled coils pass through a pickling operation where hydrochloric acid removes scale (iron oxide) from the strip surface before passing through a cold rolling mill where the strip is reduced to the final ordered thickness. The cold roll coils are then transported to a hot dip galvanizing line.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Hot-rolled coil (wide strip) products are produced by semi-continuous or continuous hot-rolling mills, which can also be a part of compact strip production plants. Continuously cast or rolled slabs made of carbon, low-alloy and alloy steel grades are used as a semi-finished product to make steel coils.
Hot rolled steel is mill process by which the steel is roll pressed at a high temperature. Generally, the temperature for hot rolled steel exceeds 1700°F. Cold rolled steel is a process by which steel is roll pressed at room temperature. It is important to note that both hot rolled steel and cold rolled steel are not steel grades.
If the cold mill rolls or hot mill coils have too little crown, the mills will roll out the edges and create edge wave (see Figure 9). This is fairly common in mill master coils. Mill work rolls and backup rolls bend and compress under the vertical loads it takes to reduce plate or sheet coil thickness.
Hot rolled coil It is a mill process which involves rolling the steel at a high temperature, which is above the steel's recrystallisation temperature. Often used in the manufacturing of staircases, the embossed teardrop pattern gives it excellent anti-slip properties, irrespective of whether the environment is dry, greasy or damp.
Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
Hot-rolled coil is made by continuously rolling the slab, after heating the slab in the reheating furnace, by the roughing mill and finishing mill, and coiled for a easier transportation.
Olympic Steel boasts a broad range of hot rolled coil, sheet and plate steel products and grades in inventory; in both Hot Roll dry and Pickled and Oiled (P&O), automotive grades, Advanced High Strength Steels (AHSS), High Strength Low Alloys (HSLA) in both ASTM and AISI standards, as well as branded products COR-TEN®, DOMEX ™, EX-TEN®, FREMAX® steel …
In the production process, the aluminum sheet and strip go from ingot to hot-rolled coil and then to the cold-rolled coil. Accordingly, it will be rolled and processed by different equipment, such as hot rolling mill, cold rolling mill, rewinding, annealing, shearing and bending, and straightening.
Hot rolled steel is steel that has undergone the rolling process at a temperature above its recrystallization temperature (usually 1700° F or greater). Compared to unprocessed steel, the processed material exhibits greater formability and workability, making it easier to work with in subsequent processing operations.
Hot rolled coil is a type of steel which is mostly used in pipe-making, construction, machinery and some other consuming sectors. Production of hot rolled coils involves melting steel at 926° Celsius, casting the melted steel into slabs and rolling them into coils. Features of Hot Rolled Coil

Hot rolled steel is usually cheaper to produce than cold rolled steel. This is mainly because the hot rolled steel is more malleable, hence you don't need heavier rollers or more production cycles to form a product. However, because its shape can shift after the process is over hot rolled steel can lead to additional reshaping expenditures ...
John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 2.7 Generation III – Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the …
